No, I think the problem existed for steppings A0, B0 and B1 and was fixed with
B2 (see also Page 13). The workaround was only necessary for A0, B0, and B1.

B2 is around for more than a year, so this problem should no longer apply.

When switching between PLL frequencies, make sure to spend some ms in a loop
before accessing SDRAM again, in order to avoid PLL overshoot.
